Hi,I have e HP Proliant G9 Server with two HDD of 1TB in RAID 1. I dont know but one of the HDD probably failed,and the system did not boot up anymore. In the two HDD i had partition C and D. If i use the 2 HDD as external from another PC,I can see only partion C.I cant understad where did partion D ,disappeared??Thanks,

Raid 1 is a mirror, missing partition does not mean that the RAID setup is bad. You may want to provide details about exactly what is happening, you said the system did not boot anymore, exactly what happens when you turn on the system, including any error messages. If a drive failed, the RAID BIOS would have seen that and given you a message about the RAID being degraded and to replace the failed disk with a good one so it can re-build the RAID.
